SPECIFICATION forming part of Letters Patent No. 698,907, dated April 29, 1902.

Application tiled .Tune 25, 1901. Serial No. 65,904. (No model.)

To @ZZ whom it' may concern.'

Be it known that I, JAMES DAKERS, a subject of the King of Great Britain, residing at Aberdeen, in lthe county of Aberdeen, Scotland, have invented certain new and useful Improvements in Bottle-Olosers, o f which the following is a full and complete specilication,` such as will enable those skilled in the art to` which it appertains to make andv use the same.4

The object of my invention is to provide a bottle-closer of a new and improved form of construction by which the closure may be rmade perfect, so as to prevent the deterioration of beers, elfervescent wines, and like liq-v nids.

stance of a bottle the interior of the `neckoriiice of which iiares outwardljr and the exterior of which neck is provided with an aunular groove or grooves; a plug of porcelain, metal, or other hard substance provided with a groove or grooves adapted to receive a suitable washer of elastic material, such as soft rubber; a protective covering of flexible material for the elastic washer, the central`por= tion of the stopper-plug being provided withi a iiange above the washer and with a centralE perforation communicating withV the hollow; interior thereof; a cap of the samematerial as the plug, larger than the orifice and clos-5' ing the extreme end of the-bottle-oriiice; twov broad base-lugs extending from the:bottl`e'` neck on opposite sides adjacent to theorifice, merging at the forward ends gradually into"y the bottle-neck, and a bail of resilient spring-A wire, the ends of which are ben-t lat right angles to the loop of the bail and: extend inward through orifices or passages formed in the bottle-neck adjacent to the lugs, so as to project over the flange of the bottlelstopper.

In the accompanyingdrawings,forming part of this specification, in which like characters of reference designate corresponding parts in the several views, Figure 1 is a side view of my improved form of-bottle andbottle-closer in positiontogether,'"and` Fig.'2'is a view of Fig. l in section on theV line c a; of Fig. l looking to the right. Fig..3 is aview of a modified formof-the construction shown in Figs. 1 and .2, and -FigQAtfis a'viewof such To such ends my invention consists in sub-V moditlcations in section on the line y y of Fig. 3 looking to the right.

Referring to the.- drawings, A designates the bottle-neck, which is provided at the top with the outwardly-haring orifice B.

C designates the bottle-stopper, which is usually formed of metal, porcelain, or any other'suitable hard material.

The stopper C consists of a top plate .l of the same diameter as is the bottle-top, which is provided upon the inner side with the inwardly-projecting annular ange 2,Which iits tightly into the orifice B. Extending downward from the central'portion of lthe plate l is the annular hollow central portion 3, ending in the annular hollow rectangular ring 4,

'which is open at the outer side and in which is placed the elastic rubber packing-ring 5, which usually is protected from the corrosive action of the liquid in the bottle bya washer 6, of any suitable soft fiexible material, such as sheepskin which is secured in place by having the inner edge '7 thereof inserted beneath the rubber packing-ring 5. Located on opposite sides ofthe bottle-neck and formed in and through the same are two perforations 8 to receive the ends 9 of the spring-bail 10, which project into the bottle-neck and over the up- 'perI outwardly-projecting flange 1l of the annular fiat-walled ringgroove 4 of the stopper -C,\as shown in Fig. 2. On opposite sides of --tle bottle-neck and located to one side of the perfo'rations B are lugs 12, each having a sloping-surfaced forward partition 13, slantin g toward the extreme end of the bottle-neck and` merging therewith at 14, and the squaresurfaced rear or bottom portion 14. Thetoperation of the device will be readily understood from the foregoing description, takeniin connection with the accompanying drawings, and the advantages resultant from the use thereof will be manifest to all who are conversant with devices of this character.

To assemble the parts, the protective sheepskin covering 6 is iirst .slipped into position by the bottom flange of "thestopper/C, and the elastic rubber washer ythen sprung into position above the saine, andthe outer por` tion of the sheepskin protecting washer turned up over the outside of the rubber IOO washer all around. The bottle having then been filled with the required liquid, the stopper C is inserted in the neck and forced fully down, vduring this operation the bail 10, of spring-Wire, being in the position shown in dotted lines in Fig. 1 and resting 011 the straight-edged rear portion 14' of the lugs 12, whereby the points 9 of the bail will be withdrawn from the interior of the bottle, so as to allow the lower part of the stopper to pass fully down into the same. As soon as the stopper has been inserted and forced fully home the bail 10 is thrown over into the position shown in full lines in Fig. 1, when the resiliency of the wire will force the ends 9 of the bail into the bottle-neck and over the flange 1l, as shown in Figs. 1 and 2, whereby suoli stopper will be firmly locked in the closed position. To remove the stopper, it is only necessary to throw this spring-bail into the position shown in dotted lines in Fig. 1, when the natural efervescence of the liquid in the bottle will at once force ont the stopper, and if such liquid is not effervescent the stopper can be easily removed by pulling upon the top cap-plate A.

In the modified form shown in Figs. 3 and 4 the central portion 3 of the stopper is of a conical form at the lower end, and the washer, which in this case is unprovided with a cover, is of a conical cup shape to lit thereover, resting at the lower end in the groove 16 and at the upper end in another groove 17. While this form of stoppermay be used with the securing-bail shown in Figs. 1 and 2, I usually prefer to provide this stopper upon opposite sides with two metallic members 18, of resilient metal, which are riveted or otherwise screwed to the top of the stopper C and extend down upon each side, ending at the bottom in inwardly-turned back end portions 19, the ends of which when in position are forced under and abut against the upper edge 20 of an exterior groove formed for that purpose in the bottle-neck.

I do not desire to confine myself to the eX- actformation of parts herein shown and described, as I conceive my invention to be novel in its plan and broad in its scope.

It is manifest that my invention may be altered or varied within lthe scope thereof.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. A bottle closure or stopper, having a capplate provided on the inside with a hollow central plug provided adjacent to the bottom with an annular groove topped by an outwardly-extending annular flange, a washer of elastic material located in the annular groove, and means coacting with the outwardly-extending annular flange for locking the stopper in position in the bottle, substantially as shown and described.

2. A bottle closure or stopper, having a capplate provided on the inside with a hollow central plug provided adjacent to the bottom with an annular groove topped by an outwardly-extending annular flan ge, a washer of elastic material located in the annular groove, a covering of flexible protective material for the washer, and means coacting with the outwardly-extending annular flange for locking the stopper in position in the bottle, substantially as shown and described.

3. In a bottle-closure, the combination with a bottle provided adjacent to the neck-orifice with two lugs extending from the bottle-neck on opposite sides provided with square bases and an upwardly-extending sloping surface slanting gradually toward and merging into the bottle-neck at the upward end, and perforations having formed in and through the side of the bottle-neck adjacent to the lugs, of a stopper provided at the inner end with an annular ring of elastic packing material, a flange located above the ring of elastic packing material, and a spi-in g-bail with inwardlyturned ends, which ends are adapted to pass through the perforations and into the neckorifice above the flange of the stopper so as to hold the same in place, substantially as shown and described.

4. A bottle closure or stopper having an outer top cap-plate adapted to abut upon the outer end of the bottle-orifice, an annular flange extending inward from the cap-plate and adapted to lit snugly into the bottle-oriflee, a'central plug extending inward from the cap having an annular groove at the inner end, a ring of elastic packing material carried by the groove, and means for securing the stopper in place in the bottle,substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 11th day of June, 1901.

JAMES DAKERS.
